SUNLIGHT SCREENING LIGHT TRANSMISSION PLATE AND SUNLIGHT SCREENING MULTIPLE LAYER LIGHT TRANSMISSION PLATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a light transmission plate having high visible light transmittance and high sunlight screening performances by successively laminating an absorption layer, a first transparent dielectric substance film, a Ag main component film and a second transparent dielectric substance film to a transparent plate. ;SOLUTION: A sunlight screening glass 30, a crosssectional block aluminum spacer 44 and a second transparent glass plate 41 in a mutually laminated state are engaged with and fixed to a fitting channel 45 of an approximately U-shaped grazing channel 43 to form a sunlight screening multiple layer glass 40. The sunlight screening glass 30 is obtained by successively laminating an absorption layer 32 (titanium nitride, etc., about 1-20 mm thickness), a first transparent dielectric substance film 33, a Ag main component film 35 (about 5-20 mm thickness) and a second transparent dielectric substance film 37 to a transparent plate a transparent glass plate 31 (float glass, polyethylene terephthalate, etc., about 1-15 mm thickness). The transparent dielectric substance films 33 and 37 are silicon nitride films, titanium oxide films, etc., an interval between the second transparent glass plate 41 and the sunlight screening glass 30 is about 6 mm to form a dried air layer 49.;COPYRIGHT: (C)2000,JPO
